Is The World Really Coming To An End In 2012?

I'm really scared because everyone told me that this 2012 the world will end. I looked on the internet and there are pages about that, a lot of people believe that this is truth and even on the TV there are some shows about the end of the world in 2012. I don't know what to think anymore, every time we talk about that I get really upset and I don't want to be like this until we know if this is truth or not. I was searching a lot but if you have real information that would be great because I'm tired of thinking that the world will really end in 2012.

I know there are a lot of pages talking about the end of the world, but also I know that most of them are not truth. I was seriously looking a lot because I wanted to be sure about what this 2012 means, with the mayan calendar and all the things everyone is saying like the galactic alignment, the change of poles, the big planet crashing with ours and the planet alignment. I searched and in a lot of pages people said that the end of the world is coming but in the official NASA page they made a whole article about what people is saying and nothing is truth.
They said that it's not going to be a planet alignment this 2012, that the earth is not going to crash with another planet because they should already known that and that the world won't change poles and if this happens, it's not a big deal.
According to specialists, the mayan calendar shows the end of a cycle but not the end of the world, and some people talk about a spiritual change more than a destruction.
So, as you can see, nothing is going to happen. You can read the NASA's article and you will realize that they are sure that this Dec. 21 will be a normal day.
